Diabetic foot ulcer is a breakdown of the skin and sometimes deeper tissues of the foot that leads to sore formation. It is thought to occur due to abnormal pressure or mechanical stress chronically applied to the foot, usually with concomitant predisposing conditions such as peripheral sensory neuropathy, peripheral motor neuropathy, autonomic neuropathy or peripheral arterial disease.

Critical limb ischemia is diagnosed by the presence of ischemic rest pain, and an ulcers that will not heal or gangrene due to insufficient blood flow. [3] Insufficient blood flow may be confirmed by ankle-brachial index (ABI), ankle pressure, toe-brachial index (TBI), toe systolic pressure, transcutaneous oxygen measurement (TcpO2 ), or skin perfusion pressure (SPP).
Some risk factors for developing diabetic foot infections include history of repeated foot ulcers, foot ulcers lasting for longer than 30 days, poor control over blood glucose levels, peripheral neuropathy, renal impairment, peripheral artery disease, injury or trauma to foot, walking barefoot frequently, and history of amputation in lower limbs.
Just over one in every ten Americans (or 34.2 million people) have diabetes and another 88 million adults have prediabetes. While many of the health risks that come with a diagnosis are happening ...
Before the ulcer establishes definitively, there may be a dark red or purple skin over the affected area as well as a thickening, drying, and itchy skin. Although skin ulcers do not seem of great concern at a first glance, they are worrying conditions especially in people with diabetes, as they are at risk of developing diabetic neuropathy.
Chronic wound healing may be compromised by coexisting underlying conditions, such as venous valve backflow, peripheral vascular disease, uncontrolled edema and diabetes mellitus. If wound pain is not assessed and documented it may be ignored and/or not addressed properly. It is important to remember that increased wound pain may be an ...
Over time, the big toe pushes outwards and alters the normal outline of the foot. Bunions occur for many reasons but the most common is not wearing proper shoes, arthritis and different inherited structural defects. Flat feet (Pes planus foot) essentially means that the arch inside the foot is flat. This very common painless disorder may occur ...
Skin cancers come in all shapes and sizes, but when it comes to identifying Basal cell carcinoma, squamous cell carcinoma and melanoma, here are a few key signs to look out for:
